/**
 * This class contains a Base64 encoder and decoder. It cannot be
 * instantiated. The encoder and decoder are based on RFC 1521, except that
 * encoder do not break up lines and the decoder will treat a line break as
 * as invalid characters. This done since MIDP JAD's can not have line breaks
 * with in an attribute. Also different RFC's use different lengths for
 * base64 strings such as; 76 for 1521, 64 for 1421, and no breaks for 2228.
 * <p>
 * For example to decode: 
 * <pre>
 *      String  encodedData;
 *      byte    binaryData[];
 *
 *      binaryData = Base64.decode(encodedData);
 * </pre>
 * This will decode the String in <i>encodedData</i> and give you an array 
 * of bytes in the array <i>binaryData</i>. 
 *
 * On errors, this class throws an IOException with the following detail
 * strings:
 * <pre>
 *    "Base64 string not a mulitple of 4"
 *    "Invalid character in Base64 string"
 * </pre>
